Relationship Between ANA Test Titers Autoimmune Disease Research Paper - 9

Relationship Between ANA Test Titers Autoimmune Disease - Research Paper Example Among the patients ‘data we collected, 13 (29.5%) patients had 40 ANA test titers, 4 (9.1%) had 80 titers, 4 (9.1%) had 160 titers, 10 (22.7%) had 320 titers, 4 (9.1%) had 640 titers, 6 (13.6%) had 1280 titers, and 3 (6.8%) had 1320 titers. This is well illustrated by both table 1 below and graph 1. During the sample, analysis three groups of diagnosis of autoimmune disease were detected. Group 1 had 13 (29.5%) patients, group 2 had 19 (43.2%) patients, and group 3 had 12 (27.3%). Table 2 and figure 2 better illustrate this Among the 13 patients who were found to fall in the category of 40 titers ANA test SLE, 2 were found to fall in group 1, 6 were found to fall in group 2, and 5 were found to fall in group 3. Among the 4 patients who were found to fall in the category of 80 titers ANA test SLE, 2 were found to fall in group 1, 1 one was found to fall in group 2, and another 1 was found to fall in group 3. Among the four in the category of 160 titers ANA test SLE, 2 were found to fall in group 1, 1 in group 2, and another 1 in group 3. Among the 10 in the category of 320 titers, ANA test SLE, 3 were found to fall in group 1, 4 in group 2, and 3 in group 3. Among the 4 in the category of 640 titers ANA test SLE, 1 was found to fall in group one while the other 3 were found to fall in group 2. Among the six in the category of 1280 titers ANA test SLE, 2 were found to fall in group 1, 2 in group 2, and 2 in group 3. Among the three in the category of 1320 titers ANA test SLE, 1 was found to fall in group 1, and the other 2 in group 2. Table 3, figure 3, and figure 4 had better illustrate this. In this project, we test the null hypothesis that the ANA and diagnosis are associated. According to Hirschfield & Heathcote (2011), the ANA test is the main testing tool used for the diagnosis of autoimmune rheumatic conditions. This test makes use of antinuclear antibodies in the diagnosing of these conditions.

Comparative Analysis of Human and Chimpanzee Genome Research Paper

Comparative Analysis of Human and Chimpanzee Genome - Research Paper Example In justification of these new findings, molecular studies have been conducted and results have indeed shown that the two species exhibit some differential characteristics, mainly contributed towards genetic changes mostly on the human genomes, which have significantly contributed towards the differences in the genomes of humans and the chimpanzees. For a substantive period, scientists have always stated that there are substantive similarities between humans and chimpanzees. History has it that human beings and chimpanzees have at one time shared a common ancestor over 5 million years ago, eliciting research on the determination of the contribution factors towards such a development (Cheng et.al. 88). As science has revealed, the genome, which is the genetic material in an organism is the contributing factor towards the determination of whether an organism possesses certain similarities or differences to other. The genome is encoded in the DNA of organisms or RNA as in the case of viruses, which includes all the genes and the non-coding sequences of a DNA or RNA. From a comparison analysis of human and chimpanzee genomes, it is conclusive that despite the similarities that the two have had from sharing an ancestor, studies have ideally shown that significant changes have occurred in the genome sequences of the two species. That has indeed contributed towards the differences that are currently observed in both the human and chimpanzee genomes. Additionally, the genomic changes have also contributed towards the diverse changes in the phenotypes of the two species of organisms.

Importance of Documentation Care in Nursing

Importance of Documentation Care in Nursing This scenario presents a number of problems to the staff nurse. In relation to the sphere of practice, as a D Grade Staff Nurse I have a senior nurse present on the ward, who will be in charge during the shift. This provides me with a source of support and experiential knowledge, and also someone with whom to liaise over any issues which arise. However, as a Registered Nurse I am responsible for my own practice, accountable for all aspects of nursing practice and therefore must act on everything pertaining to practice that should arise. In an ideal situation, the E Grade will act on any information or concerns I bring to her. If she does not, then it is my responsibility to act on these concerns myself. The NMC Code of Conduct (NMC, 2004) requires that all qualified nurses act in the best interests of their patients at all times. The NMC code of conduct also states that all nurses are accountable for their own practice, and must account for their own acts or omissions (NMC, 2004). The focus of this analysis of the scenario is on documentation and the nurse. The nursing literature suggests that the completion of nursing documentation has been one of the most important functions of nurses, even from the beginning of the profesion in the time in the time of Florence Nightingale (Cheevakasemsook et al, 2006). Documentation of nursing care is an important source of reference and communication between nurses and other health care providers (Martin et al, 1999). Documentation is a fundamental component of nursing activities such as assessment and care planning, according to the various models which have been designed for these functions (Nazarko, 2007). The importance of proper documentation may also be because it serves multiple and diverse purposes for nurses, for patients, and for the health profession, because current health-care systems require that documentation ensures continuity of care, furnishes legal evidence of the process of care and promotes and facilit ates the evaluation of the quality of patient care delivery (Cheevakasemsook et al, 2006). In this instance, following handover, the first source of information to be checked will be the nursing records and care plans of each patient, as part of an individualised approach to care. The nursing records for Mrs Smith, for example, should provide the medical history and social history which will allow me to provide holistic nursing care. However, one of the problems with nursing documentation, as found in some empirical nursing studies, is that the complexity of nursing documentation does not always allow it to serve its many functions (Cheevakasemsook et al, 2006). However, the medical record is a legal document that tells the story of the patient’s encounter with the nurse and other professional caregivers, and as such should provide a complete and accurate account of his condition and the care he received (Austin, 2006). Whatever the difficulties of the documentation processes concerned here, the documentation should have been complete and correct. Documentation issues here include the improper recording of the administration of intravenious antibiotics. Given the strong nature of this medication, their specific nature and mode of action which can be tailored to the individual disease following culture and sensitivity tests, and the need to ensure they are given at the correct intervals, particularly as some such drugs can become toxic in larger doses, the proper recording of their administration is a vital part of the administration process. Bjorvell et al (2003) in a study of 377 nurses in Sweden found that nurses believed documentation to be fundamental to nursing practice, in particular, in promoting and ensuring patient safety. Protocols for the administration of intravenous medications exist, which, if followed, should promote safety. For all medications that nurses give to patients, they must know indications, contraindications, dosage parameters and adverse reactions (Austin, 2006). Nurses must always ensure that the ordered medication is appropriate for the patient, and that the prescription is clear and legible (Austin, 2006). And once a nurse has administered a drug, they must monitor the patient for signs and symptoms of drug toxicity or other adverse reactions, and these monitoring activities must be fully documented, including any actions taken on notable findings and the patient’s response to these interventions (Austin, 2006). This creates a record which demonstrates that the nurse met the prescribed standards of patient care when administering medication (Austin, 2006). Two qualified staff should have checked the drug dosage, route and timing, and the prescription against the patient identfication band, and then recorded the adminstration of the antibiotics on the chart and in the patient records . Incomplete records in this instance could be suggestive of improper procedures in the adminstration of this medication, a serious issue which could lead to legal action and professional sanction, even dismissal and loss of registration (Austin, 2006). Similarly, the issue of the blood transfusion error should be highlighted, because again patient safety is the fundamental point of nursing care. If proper procedures had been followed, this error could not have occurred. Administration of blood and blood products is subject to strict surveillance, and each Trust will have clear guidelines and protocols which govern and support this kind of activity. Checks should have been carried out on collection of the blood – the documentation should have been checked against the blood bag – patient name, number, blood group and type. The blood form, with the number of the blood bag, should have been checked properly. This should have been carried out by two qualified staff. The same checks should have been carried out at the bedside, checked against the patient notes and his identification band. Had the documentation been checked in this way, by two qualified staff, the wrong rhesus factor blood could not have been administered. T his demonstrates how correct documentation supports safe nursing practice and facilitates patient safety as well as recording nursing actions. Not only should the mistake be rectified, the doctor in charge of the patient informed and sumoned to examine the patient, and ongoing observations be carried out to ascertain if there are any side effects from the administration of the blood, but all of this should be clearly documented. Further, it should also be documented how this mistake occurred, through an examination of the documentation pertaining to the error and the actions of those who administered the blood. All medically releveant facts realted toan incident should be recorded in the medical records, according to the Trust and ward policies and protocols (Austin, 2006). A critical incident reporting from should also be completed, according to Trust policy, in order to ensure that risk management are informed and actions can be taken to prevent such occurrences in the future. Thus, such a form should also be completed for the percieved drug error. The NMC code of conduct states that nurses should act to identify and mini mise risk to the patient or client (NMC, 2004), and this applies to the action taken in the current situation and the potential protection of all clients in the future, in the avoidance of future errors of a similar nature. Another error which relates to documentation is the issue of the patient who was discharged inappropriately. It is understandable that the relative should be distressed and should be dealt with sensitively and apologetically. Liaison with management, risk management and any hospital or Trust agencies which deal with patient complaints should commence immediately. The most important issue here is to address the error, and not to question whether or not the error took place. It obviously did, because the patient arrived home in that state, and the usual discharge protocols cannot have been adhered to. If they had been, the discharge documentation should have been complete, and would have been communicated with the receiving district nursing team. The nurse plays a unique and pivotal role in discharge planning, as a key member of a multidisciplinary team (Fielo, 1998) role. If, as Bull and Roberts (2001) suggest, a proper discharge occurs in stages, and can be characterised by involveme nt of all team members within interacting circles of communication, then this discharge error should not have taken place at all. Therefore, any work done to address this error must examine where communication processes failed, and the documentation here should provide the evidence of where this failure occurred. Communication is fundamental to discharge planning, both between nurse and patient and between professionals across the divide between hospital and community services (Fielo, 1998), and so the documentation here should have been both individualised and comprehensive, functioning both as a record and as a communication tool. Effective discharge planning is also a vital link for continuity of care (Bull and Roberts, 2001), and so the failure of this process will lead to negative impact for the patient and their carers. Similarly, patient and carer participation is important in discharge planning (McLeod, 2006; Bull and Roberts, 2001). Research by Cleary et al (2003) demonstrates that consumers want information on medication, treatment, awareness of their rights and opportunities to participate in decision making. The nurse engaging in discharge planning also needs to take into account the needs and capabilities of carers (Qualey, 1997). The failure of the discharge planning process in this case therefore has a number of complex effects and may be shown to have failed in a number of key areas. It is also imperative that nurses value the social aspects of patient care and that this is seen as an integral part of the discharge process (Atwal, 2001). There are some ways in which this could be improved, and a close examination of what went wrong might highlight ways in which this could be avoided in future cases. The discharge documentation may need to be adapted to better reflect the processes and knowledge involved (Reed, 2005). This might ameliorate relationships between the acute and community sectors (McKenna and Keeney, 2000), and may prevent these errors occurring in the future. It might also be necessary, from the evidence of the available documents relating to the case, and from the ward rota, to identify who failed to properly discharge the patient so they can be engaged in education and development activities to develop their competence in this area. The documentation used should have served to enhance the ability to deal with this difficult situation (Sollins, 2007) by providing the family with the answers to their questions about what went wrong. Cheevakasemsook et al, (2006) in their study found that complexities in nursing documentation include three aspects: disruption, incompleteness and inappropriate charting. Of these, this scenario shows occurrences of incomplete documentation, whereby the documentation related to discharge planning has not been completed. Related factors that influenced documentation comprised: limited nurses competence, motivation and confidence; ineffective nursing procedures; and inadequate nursing audit, supervision and staff development functions (Cheevakasemsook et al, 2006). These findings suggest that complexities in nursing documentation require extensive resolution and implicitly dictate strategies for nurse managers and nurses to take part in solving these complicated problems (Cheevakasemsook et al, 2006). These are learning points to take forward into future professional development and practice. However, the more immediate needs would be to address the problems associated with these fail ures. The nurse must act to redress the balance and to minimise, for example, the potential litigation which may arise from this unfortunuate situation. The family are likely to make a formal complaint, and, depending on how this has affected the discharged patient, may even take legal action for compensation. In this instance, the incomplete discharge documentation demonstrates that the required nursing care did not take place (as there is no evidence of it in the records). Therefore, legally, the nurse taking care of this patient will be liable for the errors that have occurred. There are other issues to be considered, taking the wider view, in perhaps understanding why such errors occurred and how they can be avoided in subsequent cases. Hyde et al (2005) highlight the limitations of the forms of documentation (and the forms of communciation which characterise that documentation) within nursing practice. They suggest that this nursing documentation depicts the domination of reductionist medical models, utilising scientific rationality in linguistic and communication forms, rather than reflecting the holistic nature of nursing practice (Hyde et al, 2005). Therefore the documentation may be at odds with the autonomy of the patient, bringing up issues of control and power, where the documentation may serve to exert and maintain the power of the nurse or the medical profession rather than support the wellbeing of the patient (Hyde et al, 2005). Professional autonomy on the part of nurses demands a degree of mature clinical and ethical judgement in emergent and complex situations, and it is the documentation, if correctly completed, which should also signpost this process of judgement and decision making. But if the documentation is difficult to complete, onerous or time consuming, it may be that it detracts from the quality of patient care and the easy recording of this, rather than supporting it. Documentation provides the legal protection nurses require in modern healthcare practice (Frank-Strombourg et al, 2001). Educating nurses about the principles of documentation and the importance of implementing risk-reduction practices may help guard against liability and ultimately improve patient care (Frank-Strombourg et al, 2001). Perhaps developing better charts and records, in liaison with all staff, might also ameliorate the situation. The literature demonstrates unequivocally that nurses are the professionals that patients have the most interactions with in the hospital environment (Williams, 1997). The work and competence of the nursing staff is therefore perhaps the most significant factor in determining quality of patient care (Williams, 1997), and so it is vital to ensure that nurses record their practice accurately so that their competence can be audited, and the effectiveness of their practice evaluated. If, as suggested, evidence-based practice is now at the heart of nursing care (DOH, 2001), then documentation will also allow the implementation of evidence based practice, through care protocols and pathways, and through auditing processes and reflective practice which reviews care against the available evidence. Martin et al (1999), in their research of nursing documentation activities, found that good nursing documentation supported the implementation of evidence-based practice. This takes us back to the quality of the documentation processes, and it may be that they are under development – towards evidence-based care pathways or the like, or this kind of thing may need implementing. Utilising alternative modes of documentation may also enhance practice and recording behaviours. Lee (2006) in a study of one computerised documentation system in practice, found that nurses generally viewed the content of the computerized nursing care planning system as a reference to aid memory, a learning tool for patient care, and a vehicle for applying judgement to modify care plan content. This suggests that such tools may do more than simply streamline nurses work (Lee, 2006). It may be that using a computerized care plan system can also enhance nurses’ knowledge, experience and judgement of descriptions of patient problems and care strategies (Lee, 2006). It is my opinion that it may also serve to minimise the kinds of errors that have occurred in the assignment scenario. The nature of the documentation (ie the content and structure) may therefore need to be changed. O’Connor et al (2007) show how new, streamlined nursing charts improved planning and evaluation of care and served promote patient involvement in the care and documentation processes. In reference to the discharge planning incident in particular, this might be an area to develop within the clinical area. One innovation which supports this is that described by the NHS (2007) in The Essence of Care, which was launched in February 2001, as providing a toolkit to help practitioners to implement a structured approach to sharing and comparing practice, through principles of clinical governance, enabling them to identify the best and to develop action plans to remedy poor practice. This would appear to be a key activity in the longer term to develop from the learning points contained within this problematic scenario. These kinds of benchmarks and guidelines can provide useful guidance, in association with other activities such as evidence-based care pathways and protocols, to develop more streamlined and effective practices. Another point of action is the need to carry out specific empirical research into this area. In a systematic review of research literature to test the hypothesis that care planning and record keeping in nursing practice has no measurable effect on patient outcomes, the authors were unable to identify any robust studies for review (Moloney and Maggs, 1999). This suggests that the potential effects of documentation failures cannot be fully evaluated, anticipated or described without future research. This also underlines the need to ensure the highest possible standards of care are both implemented and fully documented throughout every stage and componenet of nursing practice. This analysis shows that documentation serves a number of purposes within nursing practice. It records care, demonstrating and communicating what procedures were carried out, when, and why. It rationalises clinical decisions and evaluates clinical and nursing actions. It also allows the direction and planning of care. It provides legal proof that nurses have followed proper protocolsand procedures for the administration of medicines and blood products, for the implementation of medical and nursing orders, and in particular supports complex activities such as discharge planning. Lack of proper documentation can indicate that proper procedures were not carried out. Poor documentation can lead to confusion and to patient compromise, whereby a patient may not receive the medication required, or may erroneously receive an overdose. Similarly, the blood error could have had significant consequences, and should not have occurred, given the nature of the procedures involved, and the clear li nks between safety and existing documentation. These errors point to either a lack of competence in basic nursing procedures, or a lack of care on the part of the staff who made them. Documentation would also have supported the D grade nurse here when dealing with the problems. The discharge planning errors could have been dealt with more effectively if the documentation had been complete. This would be their primary source of information when dealing with a patient complaint and a complaint from a district nursing colleague. The expectation on all parts that such records will be complete and will answer the questions raised by all parties places the responsibility firmly on the nurse to ensure they properly fulfill this vital part of their role. Nurses can engage in proper documentation of the errors and incidents noted so that they are appropriately and comprehensively dealt with now that the errors have been identified, and so can meet all the professional requirements of their role within this siutation (NMC, 2004). And all staff can learn from these incidents, and be included in processes of research, improvement and development to implement better documentat ion and care practices in the future.

Overview of Autism Essay -- essays research papers

Autism is defined as a developmental disability of the brain. However it is not a form of mental retardation. A person with autism can actually be very intelligent. Autism develops before a child is 30 months of age. It occurs is approximately 4 out of every 10,000 children. Children with autism are unable to develop normal relationships with others. Their hearing and sight senses are heightened. A noise that would not bother a normal person might drive an autistic child crazy. They have a difficult time understanding what is going on around them. If something suddenly happens, like someone laughs or cries they go into confusion because they are wondering why this is happening and they might go into panic. Sometimes they may lose their ability to speak, or need extra time to respond to a question. It is sometimes difficult to tell whether a young child or infant is autistic. Some of the symptoms vary greatly but follow the same general pattern. Autistic infants will act relatively normal during their first few months. But after a couple of months they become less responsive to thei...

Preliminary Test and Solubility Classification of Organic Compounds

Preliminary Test and Solubility Classification of Organic Compound Keene Louise Topacio, Christopher Jay Robidillo Abstract The experiment focuses on how to classify organic compounds by its functional groups. It is done by preliminary test and with the solubility test. Preliminary test used two known compounds also the unknowns. Physical state, color, odor, and ignition test were noted. The known compounds are inorganic and organic compounds. A comparison is made from the observation in the unknown sample, by which we had concluded that there were two organic compounds and one inorganic among the unknowns. In order to have a strong background about the solubility test, we first classify organic compounds of known functional group using the said test. Butyl bromide, ethanol sucrose, butyraldehyde, ethanoic acid, methyl amine, nitrophenol, diethyl ether, benzoic acid and propanone were used. It is found out that they are class X, Sn, S, N, Sa, Sb, S, N, A1 and Sn, respectively. We use water, ether, HCl, NaOH, NaHCO3, H2SO4, litmus paper, and phenolphthalein in classifying each compound based on their solubility and color change. It follows a certain scheme on testing the compound. Each test will link to another test until we ended up with the class of that compound. We finally determine the class of the three unknowns. It is found out to be an Sb – amine -, S -salt -, and an N -aromatic compound-. Keywords: solubility, classification, organic compounds, solubility test, preliminary test Introduction One important part of experimental organic chemistry is to be able to analyze and identify an unknown organic compound from its functional groups. There are several steps in order to acquire this and there is no definite process. But there are systematic ways in different experimental organic chemistry books. For this experiment it will emphasize the preliminary examination and solubility characteristics of some known organic compounds and unknown samples. Preliminary test is basically noting informations with lesser effort compared to the other tests the physical state, color, odor, and its ignition properties. Physical state of a substance can make a distinction among organic compounds for the reason that at room temperature most of organic compounds are in its liquid state. This is due to the intermolecular forces of attraction in the compound. The color is also informative because most pure organic compounds are white or colorless. Some discolorations of brown color are effect of oxidation reaction. The odor of many organic compounds, especially the ones that have lower molar mass are highly distinctive. Also, functional groups have its' own different smell particularly alcohols, ketones, esters, aliphatic and aromatic hydrocarbons. Caution must be observed while smelling the unknown sample because large amounts of organic vapors should never be inhaled because of toxicity. The ignition test involves a procedure in which a drop or two of a liquid or about 50-100 mg of a solid is heated gently on a crucible with a bunsen burner flame. Whether a solid melts at low temperature or only upon heating more strongly is then noted. The flammability and the nature of any flame from the sample are also recorded. A yellow, sooty flame is indicative of an aromatic or a highly unsaturated aliphatic compound; a yellow but non-sooty flame is characteristic of aliphatic hydrocarbons. The oxygen content of a substance makes its flame more colorless or blue; high oxygen content lowers or prevents flammability, as does halogen content. The unmistakable and unpleasant odor of sulfur dioxide indicates the presence of sulfur in the compound. If a white, nonvolatile residue is left after ignition, a drop of water is added and the resulting aqueous solution is tested with litmus or pHydrion paper; a metallic salt is indicated if the solution is alkaline. Solubility of an organic compound in different solvents can present useful but not efficient information about the presence or absence of certain functional groups. It is because the basic principle in solubility is â€Å"like dissolves like†. In order to have a more distinct result a systematic approach can be considered and it is by solubility classification. First is to test the solubility of the unknown in water. Several structural features of the unknown can be deduced if it is water-soluble. It must be of low molar mass and will usually contain no more than four to five carbon atoms, unless it is polyfunctional. Also, it must contain a polar group that will form a hydrogen bond with water, such as the hydroxy group of an alcohol or a carboxylic acid, the amino functionality of an amine, or the carbonyl group of aldehydes or ketones. Esters, amides, and nitriles dissolve to a lesser extent, and acid. chlorides or anhydrides react with water rather than simply dissolving in it. Test in ether for water soluble compounds are also observed this is to identify further the functional groups in ther unknown. On the other hand, alkanes, alkenes, alkynes, and alkyl halides are water-insoluble. Supplementary test such as solubility in hydrochloric acid, then sodium hydroxide, sodium bicarbonate, and finally tested in sulfuric acid must be done accordingly. Solubility in one or more of these acids and bases is defined in terms of the compound being more soluble in base or acid than in water and reflects the presence of an acidic or basic functional group in the water-insoluble unknown compound. Methodology The experiment was divided into two parts and the group was given three unknowns. The first part was for the preliminary test. Data were recorded according to the physical state, color, and odor of the compound. Small amount of the test compounds, copper nitrate, acetic acid also the unknowns were placed in separate porcelain crucible. It was then heated and covered. Observations were noted. If residues were sighted it was tested for acidity or basicity using a drop of distilled water and a litmus paper. Also, a drop of 15% HCl was added to determine if there was formation of gas. Lastly, flame test using a nichrome wire was also observed in order to determine if metals were present. For the second part of the experiment, solubility class test. 1mL of the solvents; water, ether, HCl, NaOH, NaHCO3, and H2SO4, were placed on separate micro test tubes. A drop or pinch of the test compounds; butyl bromide, ethanol, sucrose, butyraldeyde, ethanoic acid, methylamine, nitrophenol, diethyl ether, benzoic acid, propanone, and the unknowns, were added to the solvent. It was then mixed and observed if it dissolved or not, miscible or not, or if there are discoloration present. The solubility flow chart was used in order to classify the compounds. Results and Discussion Preliminary test determines the physical state, color, odor, and the combustion reaction of the compound during ignition. It is shown in Table 1. That copper nitrate which is blue liquid has an odorless smell while it produces a green flame when it is ignited. On the other hand, an organic compound, acetic acid, is liquid and is colorless. It has a sour smell and it produces no residue when it is ignited. With respect with our group samples, all are in liquid state while differs in odor. A1 has a very foul odor, while A2 possess an alcohol like then A3 have a strong odor. A1 and A3 does not have a residue after it was heated it only evaporated and evolution of smelly (unpleasant) gas was also observed. In the case of A2 there were close to black residue and after ignition, a red flame was observed.

Normally, an organic compound such as acetic acid is a colorless liquid. Copper nitrate, on the other hand, is in aqueous form. Although they are in the same phase, it doesn’t mean that they have the same volatility and solubility. Upon ignition , their volatility differences are noticed. The presence of ash is observed in copper nitrate while on acetic acid there is no present. It is an indication that there was solid present in copper nitrate solution. Since a solid is not volatile, we can easily identify the presence of solid upon ignition. Thus, it is an indication that the physical state of copper nitrate is actually solid. Finally, copper nitrate has color while acetic acid has none. It is because of the presence of metal in the aqueous copper nitrate. While for our unknowns, it was all in liquid form which has an ammonia-like smell A1, alcohol like smell A2 and strong smell A3. By that, the one will know that A1 is already an amine. When it is ignited, it produces no ash and no soot. It is an indication that there is no metal present. Also, we found out that it was an organic compound because the observation was similar with acetic acid. By all obtained observation, it is possible that A1 is an amine. For A2, it was observed that it contains metal, for the reason that when it ignited the flame was red with that we could say that it is a salt. Unknown A3, was found out to be an organic compound because the observation was similar with acetic acid. We can't determine the compound with just preliminary test due to the insufficient data.

(Table 2. can identify the intermolecular forces of attraction and polarity from the structure and the functional group) Since water is a polar compound (possesses hydrogen bond) it is a poor solvent for saturated hydrocarbons. As we all know, saturated hydrocarbons are not polar because they only posses Van der Waals intermolecular force. Due to long chains (or high molecular weights) do not affect by polarity greatly; unsaturated hydrocarbons such as aromatic hydrocarbons have similar solubility with saturated hydrocarbons. The introduction of halogen atoms does not alter the polarity appreciably. It does no increase the molecular weight, and for this reason, the water solubility falls off. On the other hand, salts are extremely polar, the ones encountered in this work generally being water soluble.

The amines probably owe their abnormally high solubility to their tendency to form hydrogen-bonded complexes with water molecules. This theory is also linked with the fact that the solubility of amines diminishes as the basicity decreases. It also explains the observation that many tertiary amines are more soluble in cold than hot water. Apparently at lower temperatures, the solubility of the hydrate is involved whereas at higher temperatures the hydrate is unstable and the solubility measures are that of the free amine. Ethers, esters, ketones, aldehydes, alcohols, nitriles, amines, acids and amines may be considered together with respect to water solubility. Due to their similarity in structure with water, their solubility is high. For that, the solute-solvent interaction is strong because of their compatibility made possible by their common polarity. Because of the polar nature of water; compounds owe their solubility in it almost entirely to the polar groups which they may contain. The functional groups stated above are hydrophilic. As the hydrocarbon percentage increases, the hydrophobic part also increases. As a result, the solubility in water of these compounds containing functional groups, decreases as the hydrocarbon chain is getting longer or the ring is present. The tendency of certain oxygen-containing compounds to form hydrates also contributes to water solubility. The stability of this hydrate is therefore, a factor in determining water and ether solubility. These compounds have great solubility in water because of their capability to form hydrates. It is the reason why diethyl ether and propanone are soluble in water. On the other hand, although generally, aldehydes are soluble in water, butyraldehyde is not. It is due to long chain of the butyl hydrocarbon. For the same reason as for long chains of amines, aromatic alcohols and aromatic carboxylic acid do not exhibit solubility in water. Greater number carbon chains due to ring decreases the effect of polarity. For propanone, it doesn’t just dissolve in water. It undergo reaction which is a nucleophilic addition reaction. As a consequence, it yields a diol. As for the compounds that are water soluble, we can still further classify them through their solubility in ether. It is obtained that ethanol, ethanoic acid, methyl amine, propanone are soluble while insoluble compound are sucrose and nitrophenol. Since dipole bond is present on ether groups, it can differentiate short chain ethers, alcohols, carboxylic acid, ketone and amines from carbohydrates. Ethers cannot dissolve carbohydrates, such as sucrose. Thus, it can be classified as class S. Table 2. 3 Structure and Functional Groups of Known Compounds| Compound| Structure| Functional group| Butyl bromide, C4H9Br| | Alkyl halides| Ethanol, C2H5OH| | alcohols| Sucrose, C12H22O11| | Carbohyd-rates| Butyraldehyde| | Aldehydes| Ethanoic acid| | Carboxylic acid| Methyl amine| | Amines| Nitrophenol| | Alcohols| Diethyl ether| | Ethers| Benzoic acid| | Carboxylic acid| Propanone| | Ketone| The water soluble organic compounds that are also soluble in ether are monofunctional group compounds. We can classify their functional group base on their acidity and basicity and it is done with the use of litmus paper. When the blue litmus paper is dropped in the test compounds, only at ethanoic acid the litmus paper changes its color to red while at ethanol, methyl amine, diethyl ether and propanone. On the other hand, when red litmus paper is dropped on the test compounds, only methyl amine turned the R. L. P to blue while it remained at red for ethanol, diethyl ether and propanone. By that, we concluded that, ethanoic acid is an acid, methyl amine is a base while ethanol, diethyl ether and propanone are neutral. In the other realm, water-insoluble compounds such as butyl bromide, butyraldehyde, nitrophenol and benzoic acid are further tested with 5% HCl. It is obtained that none of these compounds are soluble in the dilute HCl. The explanation for this is that the acid can only dissolve are basic amines. Aliphatic amines (of any class) forms salts (a polar compound) when it is mixed with the dilute acid because of its basicity. 5% hydrochloric acid is also polar so they are soluble. Those compounds that dissolve in 5% HCl will probably fall under class B, which are amines. Compounds that are insoluble in 5% HCl (all compounds) are then tested with 5% NaOH. It is observed that only benzoic acid is the only soluble compound. Compounds dissolve in aqueous base solutions because they form sodium salts hat are soluble in aqueous medium. Probably, it is the only compound which is sufficiently acidic to form salt with the dilute base. Upon comparison, carboxylic acid is the functional group which is the most acidic among all organic functional group aside from sulfonic and sulfinic acids. To prove it, we can compare the acid constant of the functional group of each compound tested. The soluble benzoic acid can sti ll be classified as either a strong organic acid and as a weak organic acid. Upon mixing, it is found that it is a strong organic acid because it dissolves with the reagent. Thus, benzoic acid will fall under class A1 The compounds insoluble with 5% NaOH which are the butyraldehyde and butyl bromide and diethyl ether are further categorized. Upon mixing those compounds with the concentrated sulfuric acid, only butyraldehyde dissolves. So, butyraldehyde is on class X, while butyl bromide and diethyl ether are on class N. As we all know, butyraldehyde contains a functional group with oxygen (aldehyde), so it can undergo sulfonation with the concentrated acid. On the other hand, butyl bromide is saturated and has no functional group with O atom so it can’t undergo sulfonation. Thus it is not soluble. Table 3. 1 Solubility Test Data (Unknown) unknown| A | B | C | D | E | F | 1| | | | | | | 2| | | | | | | 3| | | | | | | A – Water, B – Ether, C – HCl, D – NaOH, E- NaHCO3, F- H2SO4 For solubility test of the 3 unknowns of the group, it is on Table 3. 1 and 3. 2, we initially confirm its solubility in water. It is found that A1 and A2 are soluble. From that, we can anticipate that our sample can be a monofunctional group compound with short chain or a carbohydrate or salts. So, the next steps for the water-soluble compounds were to check its solubility with ether. When we mixed ether and our samples were immiscible dissolves. From that, we may say that one is a salt. From the smell of the unknown A1 we already know that it will fall under amine that has a short chain so we stll tested it with litmus paper because amine are basic. It is observed that when red L. P. is exposed in the sample, it turned to blue, whereas the blue L. P. have no color change when it is exposed. It is an indication that our sample is basic. Thus, our assumptions are correct that it is a short-carbon chain, monofunctional amine and it falls under class SB. Table 3. Solubility Test Data (Unknown) unknown| 1| 2| 3| a| | | -| | | b| Pink| -| colorless| c| Sb| S| X| Possible compounds| Monofunctional alcohols, aldehydes, ketones, amides, esters, aromatic amines, nitriles, and amides with five or fewer carbons. | Salts of organic acids; amine hydrochlorides, amino acids, polyfunctional compounds with hydrophilic functional groups, carbohydrates, polyhydroxy compounds, polyb asic acids, etc. | Saturated hydrocarbons, haloalkanes, arylhalides, other deactivated aromatic compounds, diaryl ethers| a – Litmus Paper, b – Phenolphthalein, c – Solubility Class| For A3, being immiscible to water it was tested with HCl, NaOH, NaHCO3, and H2SO4 for its acidity or basicity. Unfortunately, it failed the entire tests so sum it up to a class X compound. Conclusion The objectives of the experiment were obtained. We were able to examine compounds by using the preliminary test. We were able to recognize the solubility class of each known compound given to us with the aid of solubility test. Finally, we were also able to classify organic compounds based on their solubility in some other compounds and on their acidity and basicity. The analysis and identification of organic compound for this particular experiment consists of two parts which are probably adopted from common schemes. This systematic approach enables us to have a precise analysis without spending much reagents, thus it is useful and efficient tool of identifying organic compounds. Both preliminary test and solubility test are considered. We concluded that preliminary test and solubility test are effective ways of classifying organic compounds. In preliminary test, we had seen the different properties of different compound by its physical state, color, odor and ignition test. We had compared the result of our unknown sample with the known ones, and upon comparison, we concluded that our sample is an organic compound which contains no metal. We had differentiated an organic compound from a non organic compound. An organic compound may be in a form of a solid or liquid, may be colored or not depending on the degree of conjugation, produces odor and has no ash during ignition because of the absence of metal. For our unknown sample, the significant observation is that its fishy, ammonia-like smell. Since it is an organic compound, we can say that it is an amine. By the study of solubility data it has been found possible to lay down certain generalizations which often enable one to predict the solubility behavior of a compound merely by inspection of its structural formula. In the solubility test, we found out the different class of the different organic compound. It is obtained that water soluble compounds are compounds which have a short-carbon chain compounds with monofunctional group and are carbohydrates. For ether, it is capable dissolving short-carbon chain compounds due to their common polarity. It is a way of differentiating carbohydrates from that. For those ether-soluble, their classifications are identified based on their acidity or basicity since they are monofunctional. Acidic groups are carboxylic acids, basic groups are amines while neutral groups are alcohols, aldehydes, ketones, and some carboxylic acid derivatives except the acid halides and anhydrides. For those insoluble compounds, a test for solubility with 5% HCl is made to identify strong bases such as amines that have longer chains or aromatic ring. The dilute acid can only form salt with strong bases, to dissolve. On the other hand, 5% NaOH is then used to check for the presence of acidic organic compounds. For acids, they can form salt with strong base such as NaOH, thus making it soluble. The 5% NaHCO3, which is a weak base is used to identify the degree of acidity of those obtained acidic organic compounds. Strong acidic acids are soluble with 5% NaHCO3 while weak organic acids are not. Lastly, neutral compounds with long chains or ring remained. The concentrated sulfuric acid is used in identifying functional group that has O and organic compounds that are unsaturated. Those compounds undergo sulfonation, making it soluble with the reagent. Solubility plays a major role in the identification and characterization of an organic compound. Through certain chemical tests, one can identify an organic compound. These concepts regarding the solubility of organic compounds are primarily applied in identifying the nature and properties of carbon-containing compounds as wells as predicting their behavior and reaction mechanism when allowed to be reacted with specific solvents during different chemical processes.
